Answer:
663
Step-by-step explanation:
the total number of students can be determined using this equation : 
(total ratio of Chinese and Indian students / total ratio of students) x n = 468
total ratio of Chinese and Indian students = 4 + 8 = 12
 total ratio of students 4 + 8 + 5 = 17
N = TOTAL NUMBER OF STUDENTS
12/17) x n = 468
multiply both sides of the equation by 17/12 
n = 663
 
        
             
        
        
        
m - 9 = 42
42 is our final answer so that should be by itself. 
If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.
